About coding malar bone fracture
The ICD-10-CM code for malar bone fracture is S02.400 (Malar fracture, unspecified side). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S02.400.
Within S02.40, choose S02.400 (Malar fracture, unspecified side) only when documentation doesn't support a more specific option: maxillary fracture, unspecified side (S02.401), zygomatic fracture, unspecified side (S02.402), malar fracture, right side (S02.40A), malar fracture, left side (S02.40B), maxillary fracture, right side (S02.40C), maxillary fracture, left side (S02.40D), zygomatic fracture, right side (S02.40E) and zygomatic fracture, left side (S02.40F).
Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open fracture, D for subsequent encounter for fracture with routine healing, G for subsequent encounter for fracture with delayed healing, K for subsequent encounter for fracture with nonunion and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (title revised).
